SPECIFICATION forming part of LettersPatent No. 351,496, dated October 26, 1886.

' Application filed March 13, 18 86. Serial No. 195,060. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH CONNER, ofthe city, county, and State of New York, haveinvented an Improvement in Bottle-Stoppers, of which the following is a completespecification, reference being bad to the accompanying drawings, in which 1 Figures 1 and 2 represent sectional side views of bottle-stoppers of we1l-known construction, to which my invention is intended to be applied. Figs. 3 and 4 represent simipacking is slipped upon the lower end of the stem, so as to tightly embrace and surround the same. The packing B has an outwardlyprojecting flexible flange, a, which seats against the throat b of the bottle 0. The difficulty with this kind of stopper istha-t when pressure is applied internally against the stopper the flange awill be distended or crowded outward, as is clearly shown in Fig. 2, so as to partlydraw the upper portion of the packing away from the stem A and produce an annnlar cavity, d, around said stem. This cavity will remain open to the reception of dust, insects, and other impurities during the entire period of time the bottle is'charged with gaseous liquid,'and when afterward the bottle is emptied the packing B will again close on the stem and grasp and retain the impurities which settle in the said cavity or groove d. As these stoppers, when, the bottle is being opened, are forced into the liquid contents thereof, the aforesaid impurities will become in part absorbed by the liquid, tainting the same. connected with the use of ordinary bottlestoppers. They serve to taint the liquid by the above-mentioned impurities and at all times to retain sufficient of the impurities to be objectionable in continual use. The stoppers, being within the bottle, cannot conveniently be cleaned, especially if the impurities settle, as hasbeen stated, in a cavity, which 55.

becomes subsequently closed whenever the bottle is opened.

My invention consists in providing a packing of the kind stated, and which surrounds the lower part of the stem and carries the flange a,with an upward projection, e, on the packing directly above the seat or flange portion a, so that said upwardly-projecting tubular portion e of the packing will at all times tightly hug the stem A. When pressure is applied to the stopper from within and the seat or flange portion a distended, as in Fig.

4, the tubular projection 6 will thereby be drawn down on the stem, still tightly hugging the same, all as shown in Fig. 4. By this means the objectionable open groove or cav ity heretofore referred to is avoided, and all danger of contaminating the liquid with impurities that settle in the folds of the stopper obviated.

Theinternal bottle-stopper consisting of the stem A and elastic packing B, which surrounds the lower end of said stem, and which has the flexible outwardly-extending periph 8o eral flange a and the upwardly-projecting tubular portion 6 abo'vesaid flange and around the stem, substantially as herein shown and described.
